They are thenwell washed and treated in a cold bath of water comprising two hundred fifty gallons with 4 /2 lbs. tartar emetic (C,H,O,KSbO.1/2H,O)

for 40 minutes. After this they are well washed and then cleaned in a soap bath at 160 F. The treatment is now concluded by washing. well and acidulating.

1922, Serial No. 604,390. Divided and this application 621,073. Renewed June 14, 1926.

In the above described process, basic, direct, and acid dyes are mentioned as being suitable to produce the desired shades, and it is desired to state here some examples of the dyes falling within these classes. As basic dyes may be used brilliant green, Victoria blue, rhodamine (red), thiofiavine T (yellow), and methyl violet 613 (blue) and 5B (red) as direct dyes, pontamine green BBX, diazoline dark brown, accordine seal brown; as acid dyes, fast red, milling yellow, formyl violet, formyl blue, nigrosine. This list is illustrative, not exhaustive, as other dyes may be used according to their nature and shade. It is to be understood that where I mention exact temperatures and exact working conditions, deviations may be made according to the particular circumstances and I mention such working conditions in an exact manner in order to set forth a preferred embodiment.

While the colors above listed may be produced by the use of various dyes and combinations of dyes, it is desired for the sake of specific examples, to mention dyes that may be used. Turquoise and peacock are obtained with Victoria blue and brilliant green crystals; geranium, indiana, ruby, are obtained with rhodamine B, thioflavine T, and methyl violet 5R; slate, beaver, graphite, smoke, taupe, and castor are obtained with pontamine green BX, diazoline dark scarlet, and chrysophenine G; strawberry is obtained with chlorantine violet BL and diazoline dark scarlet; emerald is obtained with brilliant green crystals and thioflavine T; plum, hunter, and myrtle are obtained with methyl violet 5R, thioflavine T, Victoria blue, and brilliant green; saXe blue, electric, sapphire, Copenhagen, delft, Japan blue, old China, are obtained with Victoria blue, methyl violet 5B, and brilliant green; prune and eggplant are obtained with methyl violet 6B plus the dyes for plum; raspberry is obtained with diazoline dark scarlet, accordine maroon, and chlorantine violet BL; national, Yale blue, and marine are obtained with Victoria blue, methyl violet 6B, rhodamine, and brilliant green; cadet and regimental are obtained with pontamine green BX and diazoline dark scarlet; olive and evergreen are obtained with Victoria blue, thioflavine T, methyl violet 5R, and brilliant green; cherry and carmine are obtained with rhodamine B and thioflavine T; bottle green is obtained with pontamine green BX, chrysophenine G, methyl violet 6B, and brilliant green; violet, pansy, and purple are obtained with methyl violet 5E, and blue purple dye: American beauty, magenta, and fuchsia are obtained with rhodaniine B, thioflavine T, and methyl violet 6B; wisteria is obtained with methyl violet 6B, brilliant green, rhodamine B, and thioflavine T; moss is obtained with Victoria blue, thioflavine T, methyl violet 5B, and brilliant green; bluebird is obtained with Victoria blue; and spring green is obtained with brilliant green and thioflavine T.

As a result of the above process there are produced varieties of dyed silk piece goods which are washable, that is, they may be washed in water containing soap at a temperature of 110 F. and they will, in most cases, stand 180 F. without suffering unevenness in shade or color. or distinct loss of color. In addition to the highly desirable quality of being washable, these piece silks have also the property of being washable without impart-ing any substantial amount of their color to the washing liquid, such as water or soap solution. These results have not hitherto been achieved with silk piece goods dyed in the colors and shades of colors above enumerated. They are also dyed evenly, that is. without irregularity in the color, or unevenness of shade. These results have not hitherto been achieved with silk piece goods and I have not only been able to attain these results in certain colors but have been able to extend them to all colors and shades thereof. The alizarine dyes, which are used for the production of fast colors in skein silk, are expensive and exist only in a limited number of shades. My new silk goods may be washed together with silk, cotton, artificial silk, wool, etc., without staining them. at a temperature of about 110 F. or higher. They also have excellent fastness to light and ironing. In the case of the present Process No. 2 they will contain a metallic mordant. such as antimony. My new piece silk goods have the properties enumerated in my aforesaid original application.

lVhile my silk piece goods have been described as being of unmixed silk, it is also possible to manufacture mixed silk goods, such as silk and cotton. by the above described process. The colors above enumerated are those appearing in the Color Card of America issued by the The Textile Color Card Association of the United States, 5th Edition.
